A To all whom t may concer/a.' Y;

Be it known that I, FRANKRioHAnDso YUBURGEss; a -citiaen'of the Dominionofv Canada, residing at Ottaw a,in the Province 'of Ontario andlDominion ofCanada, have inf vented. certain new andi useful' [Improve-;-ments in Scrub-Carts, off-which: the following is a specification,reference being,y had to the accompanying drawings, and to vthereferencecharacters marked thereon; which ffoim a part of this specification.

f This invention relates'y to an improved,

A portable kneeling bench which I-herein des'- ignateas a scrub cartf 1,fg

In scrubbing floors with aescrubbing brush and soap and water, thescrub-woman is gfpbliged to kneel upon theifloor, which being hard,promotesfSertre'rne:fatigueV and so'ref 'Iovobviate this thescrub- Jness to the knees.` woman not .infrequently employs. a' small pad orcushion to kneel upon. This is only a temporary expedient, for the pador cush-V` ion 4becomes moist and in 'timer communicates moisture tothe:clothingr of the scrub.-v woman, which adds greatly toitheannoyanceand inconvenience of the operator.

Moreover, there is no stability Vabout such.

an article and it frequently slips and slides about, making thescrubbin'goperation more difficult.,

vMy invention contemplates. a cushioned support for the scrub-woman tokneel upon, that will be comfortable and at the saine times suicientlyraised from the floor to be free from becoming moist and damp, andthuscommunicate dampness tothe clothes of the operator; a devicewhich willbe Vprovided with suitable rolle-rs so as to be readily movable as thescrubfwoi'nan proceeds with the scrubbing operation; and provided Vwithmeans whereby itmay be held `against movement in alg'ven spot while theact of scrubbing is being performed.

The nature and .advantages .of myinvention will be more readily apparentfrom an inspection of the accompanying drawings, and as I proceed withmy specification.

In said drawings:

The constructionof these casters is not terial and further descriptionwill not ybe had,"inasmuch as any caster adapted fory free movement vofthe article tov which it is ati tached, may be used.- Y It will Vbeobserved that by reason of the under members 2,y 2,

and the dependingl casters 3,3, the floor l of Y I the scrub cart israised anappreciable distance above the licor line designated by the.'numeral' 5. l/Vhile a lesser number of casters may be used, Iyrecomine1ic-l'fourfbe#V hand, the'use of four has' a tendency to check4cause this number will not-make the ,mov-jI ability of the cart toofree, Vwhile `on 'the other;

sudden movement of the cart suchas would easilyoccur if threecasterswere used.'

It will be noted that the forwardeifids'ofv thejfloor l are preferablyrounded a't` 6,' 6, Surrounding l'the two sides and' front mar-jgiiisfa'nd the rounded ends Gfof the floor'l is an upturned flangemember 7. l/Vithin this i flange member 7, and resting upon the floor 1,is any suitable padding or kneeling cushion S. To the forward end of thecart, I attach aVV suitable box 9'which may be a convenieiit receptaclefor a vscrubbing brush,

soap or other Aarticles required in the scrubbing operation.

Mounted transversely ofthe floor and in suitable journal bearings 10,10, attached to the under side of vthe transverse members 2,. 2, is'v ashaft ll. yond the outer margin of the sides of the flange 7, and ateach end is provided with a brake disk l2 as shown inV Fig. 3. The brakedisk 1 2 is mounted eccentrically of the shaft 11.` Attached to one 'ofthe eccentrically mounted brake diskslQ is a handle 14:.

VThis is preferably mounted upon the right A pair Vof out-V hand side ofthe device.` wardly projecting'pins 15, 16, are mounted This shaftextends be on the flange member 7, on the same side of the device as thehandle, and serve to limit the throw of the handle 14, as clearlyindicated by dotted and full lines in Fig. .3.

vWhen the operator is kneeling upon the cushion 8 and desires to havevthe device remain stationary, she will seize the handle 14 and move itto its forward position, indicated in full lines in Fig. 3,whereupon'the fiat faces 17 of the cam disks 12 will be presseddownwardly until in contact withl the floor. In this position allmovement of tion of the device, she will grasp the handleVV 14 and moveit backto the rear stop 16, into vthe position shown in dotted lines inFigs.

operator finds that she is entirely free from danger of accidentalslipping, andat the gin of the brake disk 12 entirely clear from theHoor. i shift the position of the scrub cartby means of the rollers anda very slight movement of the body. In kneeling, upon this device in theact of scrubbing, the voperator naturally desires to cover as large anarea as possible without shifting her position. To this end she may leanforward with out-stretched hand, and were it not for the brake disks 12,the kneeling device would slip out from undery her. With thesepbrakesapplied to the floor, there isA no danger of the device slipping away orshifting its position.

- while the brake disk 12 inname@ and described is recommended fromexperience as a practical device, I do not desire to be limited to thisparticular means ofbrake,

` as it will be `obvious that any movement resisting device may be used;and while I have shown the cushion 8 upon the support 1, it is obviousthat saidicushion may be dispensed with.

One of the principal advantages of myk invention consists in the factthat the scrubwoman when kneeling upon the cart, may

At such time the operator'mayl shift `it from point to point withoutarising susV therefrom; a simple pressure of the lhand Y sity of raisingthe body with each shift of position, the Work progresses much morerapidly. y y

' With the use offmy improved device, the

same time is provided with a soft cushioning fdevice `whereby the act ofscrubbing isfacilitated and made easier. v The device is simple inconstruction, Vcheap to manufac-` ture, and has-no parts to get out oforder; y I claim as my'invention: i As a new article of manufacture, ascrub cart comprising a support, rollers on the bottom of said support,Vay brakepmeans on the bottom of the support for locking the 'r cart in agiven position, said means comprising an eccentrically mounted brakedisk, a lever foractuatingsaiddisk and stops for limiting the movementof the lever. l
